Application filed September 6, 1921. Serial No. 498,862.

To all whom it may concern Be it known that I, ALBERTC. Flsomn, acitizen of the United States, residin at Chicago, in the county of Cookand tate of Illinois, have invented certain new and useful Improvementsin Methods of Producing Self-Spacing Shingles, of which the following isa specification.

This invention relates to covering members to be applied to a roof orother surface to render the same weatherproof, and has for its object toprovide a method of producing shingle-like covering members from sheetmaterial in a form which, when the shingles are assembled upon thesurface to be protected and in abutment along the lateral'lines of theircovered or overlapped portions, will be spacedalong the sides of theirweathering or exposed portions; also to provide shingles of this kindwhich may be reversed in position with the same effect.

In carrying out the invention, a sheet 'of material, such as roofingfelt or the like.

is punched at intervals along its inter mediate portion correspondingsubstan tially to the transverse dimensions of shingles to be formed,and is then severed upon intersecting lines, oneof which bisects theopenings transversely to their greater dimension, while other severinglines either coincide with side lines-of the apertures punched in thesheet or intersect said apertures; produced by the severing processissues in approximately quadrilateral form, but with an ofiset betweenthe exposed or weathering portion thereof and the portion which isoverlapped when in use. Repetition of the punching permits thedevelopment of offsets at opposite ends and sides of the shinle, so thatthey are reversible in position. modified method of punching consists inlocatin the apertures alternately on opposite si es of a severing linewhich afiords another method of accomplishing the same result.

In the accompanying drawing- 7 Figures 1 and 2 represent two sheetspunched in the manner stated and having indicated thereon severing linesat right angles to each other, one of which extends transversely of theapertures while the other extends longitudinally thereof, and eachcoincident with one side of an aperture in the efiect being that eachshingle Figure 1, or longitudinally through an intermediate portionthereof in Figure 2.

Figures 3 and 4 represent shingles produced by the method of punchingand cutting shown in Figures 1 and2.

Figures 5 and 6 represent shingles having offsets at opposite ends andsides rendering the shingles reversible in position with the same effectin either position as secured by the form shown in Figures 3 and 4.

Figure 7 is a view showing a modified method of punching the sheet, withthe ef fect of producing reversible shingles.

Referring to Figure 1, A represents the sheet which is punched withapertures a and severed on the 'line b which extends transverselythrough all of sai d apeltures, also on the lines 0 which coincide withthe respective apertures; in this instance with one side thereof. The,result of this method of punching and cutting is the right hand shingleD (Figure 3), together with its overlapping portion d of full width,weathering portion d of narrower width, and the offset d between saidportions; also the left hand shingle E (Figure 4:) withits broaderoverlapping portion 6, its narrower weathering'portion c, and its offset6 Shingles such as those represent ed by either D or E, when all of thesame kind, can be placed side by side with their broad longitudinalmargins in abutment and their offsets d all presented in the samedirection and the result will be spaced weathering portions 0! in thecase of shingles D, or a similar arrangement in the case of shingles E.

As shown in Figure 7, apertures 01., a may be formed alternately onopposite sides of the severing line 0' and the severing lines b followedas in the previous instance, with theresult that reversible shingles Fand G will be provided, either end of which may be used as a weatheringportion or an overlapping portion, and with the result that if all theshingles used are of the single type F, single spaces will result fromthe offsets F, or if of the single type G, single spaces will resultfrom the offsets 9 but if the forms-F and G are used alternately,spacings equivalent to the offset f plus the offset g may be developedin line with each alternate longitudinal abutment while eachintermediate longitudinal abutment is without spacing.

The foregoing are only some of the uses that may be served by shinglesproduced in the manner described, but will sufiice to illustrate theinvention.

I claim:

1. The method of producing shingles from sheets, which consists inpunching a sheet at intervals corresponding substantially to the widthof shingles to be produced, severing said sheet on a line extendingtransversely of a series of apertures so formed to 'produce reducedshingle ends, ,and also severing said sheet on lines producing sideedges which meet said apertures.

2. The method of producing shingles from sheets, which consists inpunching a sheet at intervals correspondirg substantially to the widthof shingles to be p'oduced, severing saidsheet on a line extendingtransversely of a series of apertures so formed to produce reducedshingle ends, and also severing said sheet on lines producing side edgeswhich meet said apertures; a severing line extending in the longitudinaldirection of an aperture being in a cutting plane which lies between theside lines of said aperture.

3. The method of producing shingles from sheets, which consists inpunching a sheet at intervals corresponding substantially to the widthof shingles to be produced, severing said sheet on a line extendingtransversely of a series of apertures so formed to produce reducedshingle ends, and also severing said sheet on lines producing side edgeswhich meet said apertures; a severing line which extends in thelongitudinal direction of an aperture being coincident with one sidethereof.

4. The method of producin shingles from sheets, which consists in puncing a sheet at intervals corresponding substantially to the width ofshingles to be produced, severing said sheet on a line extendingtransversely of a series of apertures so formed to produce reducedshingle ends, and also severing said sheet on lines producing side edgeswhich meet said apertures; a severing line which extends in thelongitudinal direction of an aperture being coincident with one sidethereof; and the rows of'apertures being multiplied and those inalternate rows lying on opposite sides of the severing lines whichcoincide with the side lines of said a ertures.

In testimony whereof I have ereunto signed my'name.

ALBERT C. FISCHER.
